A violência é um problema de saúde pública e sua notificação é fundamental para a vigilância epidemiológica e para a definição de políticas públicas de prevenção e promoção de saúde. O estudo objetivou caracterizar a ocorrência de violência doméstica, sexual e de outras, a partir das informações do banco de dados do Sistema Informação de Agravos de Notificação (SINAN), das fichas de notificação de violência da cidade de Belém (PA), no período de janeiro de 2009 a dezembro de 2011. Foram sistematizadas 3.267 notificações, representando um aumento de 240% de 2009 a 2011. Em relação ao sexo das vítimas, observou-se que, em média, 83,2% dos casos atingiram as mulheres, proporção esta semelhante nos três anos analisados. A violência sexual foi a mais presente com 41,8%; seguida da violência psicológica com 26,3% e da violência física com 24,0%. Os resultados demonstram a importância do conhecimento do perfil das violências para intervenção e elaboração de políticas públicas intersetoriais que promovam a saúde e a qualidade de vida nesta região do Brasil.

Health literacy, a more complex concept than knowledge, is a required capacity to obtain, understand, integrate and act on health information [1], in order to enhance individual and community health, which is defined by different levels, according to the autonomy and personal capacitation in decision making [2]. Medium levels of Health literacy in an adolescent population were found in a study conducted in 2013/2014, being higher in sexual and reproductive health and lower in substance use. It was also noticed that the higher levels of health literacy were in the area adolescents refer to have receipt more health information. The health literacy competence with higher scores was communication skills, and the lower scores were in the capacity to analyze factors that influence health. Higher levels were also found in younger teenagers, but in a higher school level, confirming the importance of health education in these age and development stage. Adolescents seek more information in health professionals and parents, being friends more valued as a source information in older adolescents, which enhance the importance of peer education mainly in older adolescents [3]. As a set of competences based on knowledge, health literacy should be developed through education interventions, encompassing the cultural and social context of individuals, since the society, culture and education system where the individual is inserted can define the way the development and enforcement of the health literacy competences [4]. The valued sources of information should be taken into account, as well as needs of information in some topics referred by adolescents in an efficient health education. Schizophrenia is a serious and chronic mental illness which has a profound effect on the health and well-being related with the well-known nature of psychotic symptoms. The exercise has the potential to improve the life of people with schizophrenia improving physical health and alleviating psychiatric symptoms. However, most people with schizophrenia remains sedentary and lack of access to exercise programs are barriers to achieve health benefits. The aim of this study is to evaluate the effect of exercise on I) the type of intervention in mental health, II) in salivary levels of alpha-amylase and cortisol and serum levels of S100B and BDNF, and on III) the quality of life and selfperception of the physical domain of people with schizophrenia. The sample consisted of 31 females in long-term institutions in the Casa de Saúde Rainha Santa Isabel, with age between 25 and 63, and with diagnosis of schizophrenia according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR). Physical fitness was assessed by the six-minute walk distance test (6MWD). Biological variables were determined by ELISA (Enzyme-Linked Immunosorbent Assay). Psychological variables were assessed using SF-36, PSPP-SCV, RSES and SWLS tests. Walking exercise has a positive impact on physical fitness (6MWD -p = 0.001) and physical components of the psychological test...

Gastric cancer is the fourth most frequent type of cancer and the second most frequent cause of cancer mortality worldwide. Only a modest number of gastric carcinoma cell lines have been isolated thus far. Here we describe the establishment and cytogenetic characterization of three new gastric cancer cell lines obtained from primary gastric adenocarcinoma (ACP02 and ACP03) and cancerous ascitic fluid (AGP01) of individuals from northern Brazil. ACP02, ACP03, and AGP01 cell lines are presently in the 60th passage. The cell lines grew in a disorganized single layer with some agglomerations and heterogeneous divisions (bipolar and multipolar). All cell lines exhibited a composite karyotype with several clonal chromosome alterations. Trisomy 8 was the most frequent alteration. Chromosome 8 aneusomy was confirmed by fluorescence in situ hybridization. All cell lines also exhibited trisomy 7 and deletion of chromosome arm 17p. These results suggest that, although frequent chromosome alterations are commonly observed due to culture process, the ACP02, ACP03, and AGP01 cell lines and primary gastric cancer from individuals of northern Brazil share genetic alterations, supporting use of these cell lines as a model of gastric carcinogenesis in this population.

ResumoA violência contra crianças e adolescentes é um desafio para área da saúde e os profissionais tem um papel importante nesse contexto. O presente estudo objetivou caracterizar a percepção de profissionais de saúde sobre violência contra crianças e adolescentes e suas dificuldades para o manejo desse fenômeno. Foi realizado um estudo descritivo com 72 profissionais de saúde da atenção básica do município de Belém-Pará-Brasil. Em relação aos tipos de violência a negligência foi a mais referida pelos profissionais (60,74%)seguida da violência sexual (24,14%), da física (39,47%) e a psicológica (34,88%), porém a mais notificada foi a sexual (50%). Em relação à ficha de notificação (50,00%) dos participantes disseram que não a conhece e 86,11% nunca a utilizaram. Os resultados sugerem que há necessidade de capacitação permanente e de condições instrumentais adequadas para fortalecer a atuação dos profissionais de saúde a superarem os desafios que a intervenção em casos de violência exige. Palavras-chave: violência, crianças e adolescentes, profissionais de saúde Identification and reporting of violence against children and adolescents: limits and possibilities of action of health professionals AbstractViolence against children and adolescents is a challenge for health and professionals play an important role in this context. This study aimed to characterize the perception of health professionals about violence against children and adolescents and their difficulties in managing this phenomenon. A descriptive study was carried out with 72 health care professionals from the city of Belém-Pará-Brazil. Regarding the types of violence, negligence was the most reported by professionals (60,74%) followed by sexual violence (24,14%), physical violence (39,47%) and psychological violence (34,88%). The most reported was sexual (50,00%). Regarding the notification form (50,00%) of the participants said that they did not know it and 86,11% never used it. The results suggest that there is a need for permanent training and adequate instrumental conditions to strengthen the performance of health professionals to overcome the challenges that intervention in cases of violence requires.

Very satisfactory results have been obtained with the treatment of sickle cell anaemia with hydroxyurea (HU), an antineoplastic drug. This is because it significantly increases the levels of foetal haemoglobin. Nevertheless, inadequate dosages or prolonged treatment with this pharmaceutical can provoke cytotoxicity or genotoxicity, increasing the risk of neoplasia. We monitored patients under treatment with HU for possible mutagenic effects, through cytogenetic tests (mitotic index and chromosome aberrations) for one year. Checking at two-month intervals, the cytotoxic effect was not evident. There was no evidence of genotoxicity under the conditions of our experiment. However individuals treated with HU should be constantly monitored, as an absence of genotoxicity could be transitory; the mitotic index should also be observed, as an indicator of cytotoxicity.

Twelve breast fibroadenomas were analyzed cytogenetically and only four were found to have clonal alterations. The presence of chromosomal alterations in fibroadenomas must be the consequence of the proliferating process and must not be related to the etiology of this type of lesion. In contrast, the few fibroadenomas that exhibit chromosomal alterations are likely to be those presenting a risk of neoplastic transformation. Clonal numerical alterations involved chromosomes 8, 18, 19, and 21. Of the chromosomal alterations found in the present study, only monosomy of chromosomes 19 and 21 has been reported in breast fibroadenomas. The loss of chromosome 21 was the most frequent alteration found in our sample. The study of benign proliferations and their comparison with chromosome alterations in their malignant counterparts ought to result in a better understanding of the genes acting on cell proliferation alone, and of the genes that cause these cells to exhibit varied behaviors such as recurrences, spontaneous regression and fast growth.
